How To Fix A Traulsen Freezer That’s Not Cooling Properly

A Traulsen freezer is a great appliance for many commercial kitchens because it is durable and efficient at keeping food at the right temperature. But like all equipment, it can suffer from problems over time. The most common problem is in cooling, which can be due to faulty Traulsen freezer parts, lack of maintenance, or external factors. In this article, we will explain the most common reasons why a Traulsen freezer isn’t cooling properly, and how to solve these problems so that your kitchen stays operational and your food is stored properly.

Causes and Fixes for a Traulsen Freezer Not Cooling Properly

Here are the common causes and fixes for a Traulsen freezer not cooling properly, helping you troubleshoot and resolve the issue efficiently.

1. Thermostat Malfunctions

The internal temperature of a freezer is maintained through a thermostat. If it malfunctions or is not correctly set, the temperature inside the freezer will not be maintained at the level desired.

Fix:

• Examine the Thermostat Settings: Confirm thermostat settings, which should normally be between -10°F and -20°F (-23°C and -29°C).

• Test the Thermostat: Measure the resistance using a multimeter. The thermostat must be replaced if it malfunctions.

2. Excessive Frost Build-up

If the evaporator coils become too frosty, it can keep airflow from happening and not cool properly. This usually means that the freezer's defrost system is having issues.

Fix:

• Defrost the Coils: Unplug the unit if you see too much frost build up inside the freezer and let the ice melt. Using warm water or a hair dryer can speed up this process. Once defrosted, see if the freezer goes back to normal operation.

• Check the Defrost System: If frost is persistent, look to defrost timer, defrost heater, and defrost thermostat. Any of these components could be malfunctioning and need to be replaced

3. Dirty Condenser Coils

The heat from the cooling process is released by the condenser coils. The freezer's capacity to chill efficiently may be hampered if these coils are unclean or dusty.

Fix:

• Locate the condenser coils, which are often located on the back or underneath the freezer, after removing them from the wall. Use a coil brush or a vacuum with a soft brush attachment to remove grime, dust, and oil. This will make the system run smoothly.

• Check the Fan Motor: Also, check that the fan motor is working properly and clean the coils. The fan will need to be cleaned or replaced if it’s clogged or is not running.

4. Compressor and Start Relay Issues

The compressor, which circulates refrigerant and keeps the temperature frigid, is the central component of the refrigeration system. The freezer won't chill down adequately if it's not functioning properly. Similarly, the compressor may not start due to a malfunctioning start relay.

Fix:

• Listen for Compressor Sounds: Listen for humming or clicking noise when the freezer is running. If the compressor makes no sound, it may have failed.

• Test the Start Relay: Test the start relay for continuity with a multimeter. If it cannot show continuity, it could need to be replaced.

• Inspect the Compressor: If the compressor is the problem, it’s usually best to have a professional technician check it out since compressor replacement is a job that requires expertise and special tools.

5. Refrigerant Leaks

Low levels of refrigerant may be the source of your freezer's cooling issues. Refrigerant leaks are the most common cause of this happening because the system can’t maintain the proper pressure and temperature.

Fix:

• Look for Signs of Leaks: Look around the evaporator and condenser coils for oily residue, which could be a sign of a refrigerant leak. Although refrigerant leaks are serious, they can cause system failure.

• Make a Professional Technician contact: It's critical to make a qualified technician contact if you suspect a refrigerant leak. They can find the leak, fix it, and change the amount of refrigerant. This is not a DIY fix as you need special tools and certifications to handle refrigerants.

6. Faulty Door Seals

Defective or worn-out door seals allow warm air to enter the freezer, making it harder for the device to keep the right temperature.

Fix:

• Inspect the Door Seals: Check for cracks, tears, or any areas where the seal doesn’t make full contact with the door. Air leakage from a broken door seal might make the freezer work harder.

• Replace the Seals: Replacing the seals is an easy fix if the seals are damaged. Most Traulsen models have replaceable door gaskets, and a new seal can restore cooling performance and increase energy efficiency.

If you own a Traulsen freezer, cooling issues can quickly disrupt your kitchen operation, so it’s important to address these issues quickly. Maintenance and troubleshooting of your freezer should be regular to ensure your freezer lives long and to avoid any major problems. If the problem is more complicated, don’t hesitate to ask a professional technician for the best performance and food safety.
